TPR and family visits

' Great Grandma ' would be the ' Mom's Grandma ' ? What is her relationship to the child? Are you able to prove ? The behavior (s) are directly related to the visits? I would question and this should be documented ? What occurs during the visits? Most states would rule in favor of ' Great Grandma ' without ' batting an eye ' ...Does the child have cognitive ability to understand what the visits are about ?? Why are the visits under supervision also ???
